No percentages here. This company's share count has moved by a factor of 2.1 over the window, from 49,951,466 to 103,704,809 shares. A split, a merger or a large issue changes what the company is, and a holding measured at one point in that run is not a fraction of it at another.

Nothing of that kind in this period.
